Hello Head-Fi!
We’re thrilled to announce an all-new earphone for reference-level listening when every detail matters: the IE 900. Made in Germany and milled from a single block of aluminum, each earpiece houses a sophisticated multi-stage acoustic system that pushes our wide band dynamic transducer technology into new realms of real-world performance. With striking clarity and liquid-smooth response throughout the frequency spectrum, the IE 900 offers a remarkably cohesive sound eager to please the modern audiophile.
Every Detail Matters
The IE 900 was built without compromise for a transcendent listening experience. Crafted from a single block of aluminum, each earpiece was designed to house the X3R transducer system—a combination of our 7mm TrueResponse extra wideband transducer and a triple-chamber frequency absorber. Together, they reveal the kind of surreal details that satisfy the most demanding listener, packaged in an anodized housing worthy of the high-performance acoustical system within.IE 900 features:
- Striking clarity across the entire frequency range with the cohesive presence of a full-size headphone, in a compact in-ear format
- TrueResponse 7mm dynamic transducer for extra wideband performance with utmost phase integrity and ultra-low distortion
- Triple-chamber frequency absorber removes masking energy spikes from frequency clusters to reveal layer after layer of detail
- Acoustic vortex in each exit nozzle randomizes soundwave reflections for extended, fatigue-free listening sessions and a pleasingly natural sound stage
- Unique back-volume manages air flow behind the transducer for sublime low-frequency performance
- Each earpiece is milled from a single block of aluminum using a 5-axis CNC process to achieve the necessary tolerances required for the advanced acoustical system
- Anodized aluminum fuses long-term durability with an aesthetic unique to each unit produced
- Assembled by hand at Sennheiser’s German headquarters, even using specialized cameras to aid in component placement
- Sealed, noise-isolating fit with 3 sizes each of silicone and viscoelastic memory foam adapters (S/M/L)
- Ships with three cables: single-ended cable with 3.5mm plug termination, balanced cable with 4.4mm pentaconn plug termination, and balanced cable with 2.5mm termination
- Cables are para-aramid reinforced with Fidelity+ MMCX connectors
- Recessed cable sockets for improved strain relief and long-term durability
- Adjustable ear hooks for a secure, comfortable fit
- 5 Hz - 48,000 Hz frequency response
- Efficient 16 Ω impedance for use with a wide range of audio sources
- Remarkable clarity at both SPL extremes with <0.05% THD (1 kHz, 94 dB)
- Up to 123 dB SPL sensitivity (@1 kHz / 1 Vrms)
- Protective, serialized rigid travel zip case, microfiber cloth, cable clip and cleaning tool included

We invite you to watch the Making Of video, giving you a closer look into the process of developing the IE 900.Air to the Throne
The IE 900’s remarkable clarity comes from a harmony of systems at work to unlock the masterpieces buried within every track, every time. Our single, high-performance dynamic driver avoids the sonic obstacles introduced by multi-driver arrays such as phase incoherence and distortion from overlapping frequency bands. Each earpiece houses a unique Triple Chamber Absorber (an update to the patented dual-chamber absorber that debuted in the IE 800) which pinpoints and tames resonance peaks that mask a recording’s unique textures. This frequency smoothing brings the listener ever closer to a perfect sound experience—the reproduction of an entire moment captured through sound and nothing more.A miniature back volume is used to manage the direction and overall volume of air behind the transducer for a dramatic increase in low-frequency intelligibility. To further prevent the unwanted buildup of acoustical energy, the IE 900 scatters soundwaves using an acoustic vortex milled into the nozzle. The results are a natural, fatigue-free sound without sacrificing the detail uncovered earlier in the chain.

Precision x Integrity
From start to finish, the IE 900 is crafted with industry-leading integrity at our world-class production facility in Germany. Aluminum and the five-axis CNC milling process present the capability to achieve granular precision and long-term beauty while incorporating the aforementioned acoustic treatments. Each transducer is exhaustively mated to its stereo companion in a process that virtually eliminates unit-to-unit variances. During assembly, hand-select components are even monitored with specialized cameras to ensure their placement is nothing short of perfect.
It’s All About Connection
Included with every IE 900 are three para-aramid reinforced cables: a single-ended cable with a 3.5mm plug termination, as well as a balanced cable with a 2.5mm plug and a balanced cable with a 4.4mm Pentaconn plug. The IE 900 uses gold-plated Fidelity+ MMCX connectors that provide utmost contact integrity. Each housing-side receptacle is seated within a recessed, 4.8mm-wide socket to provide wearers with robust strain relief. Three sizes of silicone and viscoelastic eartips ensure a comfortable coupling for optimum bass response and environmental isolation. A microfiber cleaning cloth, debris cleaning tool and clothing clip stash away in the serialized, zippered storage case so you can take the IE 900 on all of your travels.See the IE 900 from every angle
This new earphone will be available in Europe, North America, China and Japan starting in early June. The IE 900 will be available in most other markets including Dubai, Russia, South America, and select Asia-Pacific markets in early July. Pre-orders in Europe, Africa, North America and the Middle East are open today. We will provide further updates as soon as possible, right here. For more information, visit sennheiser.com or contact your local Sennheiser dealer. Pricing and Preorder button will be added Tuesday, May 11. We can’t wait for you to hear it.
